Navigation shoe special for blind person

Abstract

The invention relates to a navigation shoe special for a blind person. The navigation shoe comprises a shoe body, a wireless Bluetooth headset and a voice player, a navigation chip is arranged in the shoe body and connected with an infrared sensing probe arranged at the front end of the shoe body, an LED light emitting unit connected with a control device is arranged on the outer surface of the shoe body, and an isolating device is arranged on a pin of the LED light emitting unit. Compared with the prior art, the navigation shoe has the advantages that the blind person can sense road conditions through the navigation chip, and the infrared sensing probe on the shoe can give out different sensing signals and generate jittering of different degrees according to size and position of obstacles in front of and beside the blind person so as to help the blind person to effectively avoid the obstacles; the LED light emitting unit is arranged on the outer surface of the shoe body, so that when walking on a road, the blind person is enabled to be capable of receiving more attention and more help from the society and other people.

Description

technical field [0001] The invention relates to a shoe, in particular to a special navigation shoe for the blind. Background technique [0002] Blind people are a disadvantaged group in society. Although blind people have blind canes to explore the way, they cannot navigate the direction of walking and walking routes only with crutches or guide dogs. Obstacles, others are simply unable to guide the blind correctly. [0003] For example, it is often unsafe for a blind person to use crutches to travel alone. The navigator installed in the crutches is sometimes prone to shaking when the blind person walks, turns his head or does some actions, which interferes with the launch and greatly affects the results obtained. , its accuracy rate is not high, so it is necessary to update the current navigation tools for the blind to safely navigate for the blind.

Problems solved by technology

[0002] Blind people are a disadvantaged group in society. Although blind people have blind canes to explore the way, they cannot navigate the direction of walking and walking routes only with crutches or guide dogs. Obstacles, others are simply unable to guide the blind correctly

[0003] For example, it is often unsafe for a blind person to use crutches to travel alone. The navigator installed in the crutches is sometimes prone to shaking when the blind person walks, turns his head or does some actions, which interferes with the launch and greatly affects the results obtained. , its accuracy rate is not high, so it is necessary to update the current navigation tools for the blind to safely navigate for the blind

Therefore, in order to improve the defects of traditional crutches, some products with sound-producing voice functions have appeared on the basis of traditional crutches. Their deficiency is that although the former has voice prompts, blind users can only know their surroundings However, if you don't know the road conditions, you still can't feel free to explore the road by yourself. In addition, once the navigator breaks down, you can't use it immediately, and it may even endanger safety due to misleading. The latter also has the hidden danger of navigator failure. Moreover, the relevant information of road conditions cannot be transmitted to the blind, and the blind cannot know it immediately, so it is still inconvenient to use

[0005] The above-mentioned guide shoes for the blind have the following defects: one, although this type of shoes solves the situation that the blind can know the road surface well, but gives the prompt of the road information to the blind through the loudspeaker, sometimes the sound of the loudspeaker is too small to affect the blind to perceive the road information in time, and cannot Really serve the purpose of helping the blind to reach their destination smoothly

2. After the blind wear this kind of guide shoes, the effect is the same as that of ordinary people wearing shoes. From the perspective of passers-by, they cannot be distinguished as blind, which leads to the fact that blind people cannot get more support from society and others when they are walking on the road. Follow and help

Although similar light-emitting shoes have appeared on the market, such as a Chinese utility model patent "A Self-Controlling Sound and Light Shoes" with a patent number of ZL97250071. Composed of a lighting device, it is characterized in that the sound and light automatic control device is installed on the surface of the shoe, and the lighting device is installed on the front end of the shoe. The lighting prompt of the lighting device is conducive to attracting the attention of passers-by, but it does not have a navigation function. Moreover, the pins of the LED lights in the lighting device are directly exposed on the circuit board, there is a risk of short circuit of the pins, and the service life of the lighting device is very short.
